Practicing History Podcast Episode 4: Correlation

Sorry that I was unable to post an episode of Practicing History last week. It's the final few weeks of summer, and I was trying to finish up some research before the term begins.
Today's episode is the second of a two-part series on correlation and causation. You can listen to them as standalone episodes, but I think that they do a good job at reinforcing each other.
